Embodiment 1

[0031] Example 1: A centerline glue for cigarettes, consisting of the following raw materials: 50 kg of polyvinyl alcohol, 500 kg of deionized water, 2 kg of defoamer, 1 kg of preservative, 10 kg of urea, and 10 kg of wood pulp paper.

Embodiment 2

[0032] Embodiment 2: A kind of middle line glue for cigarettes, is made up of the raw material of following weight: polyvinyl alcohol 200kg, VAE emulsion 100kg, deionized water 800kg, defoamer 5kg, preservative 5kg, urea 100kg, wood Pulp paper 150 kg.

[0033] The method for preparing the centerline glue for this cigarette is as follows:

[0034] Add 450 kg of deionized water into the ceramic reactor, raise the temperature to 70°C, slowly add 200kg of polyvinyl alcohol, heat up to 90°C to completely melt the polyvinyl alcohol to obtain an aqueous solution of polyvinyl alcohol, and keep it in the reactor for 60 ℃ for use, and the holding time should not exceed 4 hours;

[0035] Step 2: Add 150 kg of wood pulp paper into the stirring tank, soak for 30 minutes and then start stirring, so that the wood pulp paper is completely dispersed in 250 kg of deionized water, after the dispersion is complete, use a 200-mesh filter to filter the filtrate as a wood pulp dispersion available...

Embodiment 3

[0040] Embodiment 3: a kind of middle line glue for cigarette, is made up of the raw material of following weight: polyvinyl alcohol 120 kg, VAE emulsion 50 kg, deionized water 673 kg, defoamer 2 kg, preservative 5 kg, urea 50 kg, Wood pulp paper 100 kg.

[0041] The method for preparing the centerline glue for this cigarette is as follows:

[0042] Add 400 kg of deionized water into the ceramic reactor, raise the temperature to 70°C, slowly add 120 kg of polyvinyl alcohol, heat up to 90°C to completely melt the polyvinyl alcohol to obtain an aqueous solution of polyvinyl alcohol, keep it warm in the reactor Stand-by at 60°C, the holding time should not exceed 4 hours;

[0043] Step 2: Add 100 kg of wood pulp paper into the stirring tank, soak for 30 minutes and then start stirring, so that the wood pulp paper is completely dispersed in 200 kg of deionized water. After the dispersion is complete, use a 200-mesh filter to filter the filtrate as a wood pulp dispersion availabl...

Abstract

The invention relates to the technical field of gluing, particularly relates to a middle line glue for cigarettes, and a preparation method thereof, wherein the middle line glue comprises the following raw materials by weight: 50-200 parts of polyvinyl alcohol, 0-100 parts of a VAE emulsion, 500-800 parts of deionized water, 2-5 parts of a defoaming agent, 1-5 parts of a preservative, 10-100 partsof urea and 10-150 parts of wood pulp paper. According to the invention, the middle line glue and cigarette bobbin paper have good cohesiveness, while the fibrous films formed by the middle line glueare connected in an interwoven mode and are not likely to permeate out of the bobbin paper, so that the middle line glue cannot permeate out of the bobbin paper.

Description

technical field [0001] The invention relates to the field of gluing technology, in particular to a centerline glue for cigarettes and a preparation method thereof. Background technique [0002] With the continuous improvement of cigarette technology and people's higher pursuit of cigarette quality, the permeability of cigarette paper used for cigarette materials is also continuously improved and has reached 12000cu. At present, the centerline adhesive for cigarettes used in China has been unable to bond the coil paper with such a permeability, and the phenomenon of machine shutdown for cigarettes due to the penetration of the centerline glue occurs frequently. How to avoid the frequent downtime of cigarette machinery due to the glue penetration of the center line is an urgent problem for major adhesive manufacturers to solve. Contents of the invention [0003] The object of the present invention is to provide a centerline glue for cigarettes and a preparation method there...
